Doctor Clack point-of-entry (POE) Aerating Iron Oxidizer (AIO) filter systems function as a regenerable water treatment unit utilizing oxygen instead of potentially harmful chemicals to rejuvenate and enhance the performance of the selective filtration media. The filtration media provided is specific to the water contaminant or contaminants that your water treatment specialist has identified.

The AIO system utilizes the Clack WSlEE control valve equipped with air injection capability to remove ferrous (or clear water) iron, manganese, and sulfur from the water by both oxidation and filtration. During the regeneration cycle, an air bubble is established in the head space of the filter tank above the media. Then, during service, as untreated water enters the tank, it mixes with the air. Oxygen present in the air oxidizes some of the iron and managese that are present in the water, causing them to precipitate into particles which become trapped in the filter media. The remaining dissolved iron and manganese precipitate out in
the filter bed as they are oxidized by the catalytic reactions occurring on the media surface. 

Unlike other iron filter alternatives, the Clack WSlEE AIO technology is designed for use in a single tank / valve system configuration, reducing both installation and maintenance costs, yet delivering years of trouble-free service. No chemical additives or air compressors are required for operation or regeneration with the Clack WSlEE AIO’s unique and advanced design.
